abstract = {Mnemonic discrimination (MD) is the ability to distinguish
current experiences from similar memories. Research on the
brain correlates of MD has focused on how regional neural
responses are linked to MD. Here we go beyond this approach
to investigate inter-regional functional connectivity
patterns related to MD, its inter-individual variability and
training-related improvement. Based on prior work we focused
on medial temporal lobe (MTL), prefrontal cortex (PFC) and
visual regions. We used fMRI to determine how connectivity
patterns between these regions are related to MD before and
after 2-weeks of web-based cognitive training. We found
MD-related connectivity involving MTL-PFC-visual areas.
Hippocampal-PFC connectivity was negatively associated with
inter-individual variability in MD performance across two
tasks. Hippocampal-PFC connectivity decrease was also linked
to inter-individual variability in post-training MD
improvement. Additionally, training led to increased
connectivity from the lateral occipital cortex to the
occipital pole area. Our results point to a hippocampal-PFC
connectivity pattern that is a reliable marker of MD
performance. This pattern is further related to MD training
gains providing strong evidence for its role in
distinguishing similar memories. Overall, we show that
hippocampal-PFC connectivity constitutes a neural resource
for MD that enables training-related improvement and may be
targeted to enhance cognition.},
